What Causes Sudden Insomnia, Nightmares And Altered Sense Of Smell?

Insomnia and nightmares are due to depression only
Detailed Answer:
Hello thanks for asking from HCM
I can understand your concern and it appears that depressive disorder is the main reason for your symptoms like poor sleep, night mares, anger episodes and altered smell. In depression REM sleep (a type of sleep) increases in duration which is light sleep and this results in non refreshing sleep with nightmares. Poor control of depressive symptoms results in these symptoms.
I will advise you to consult your psychiatrist again for reevaluation. If you have not taken any medicines then medicines like SSRIs as Paroxetine, or other medicines like Mirtazapine etc can help. These medicines will reduce your symptoms of depression and will also reduce nightmares. Apart from this medicines like Ramelteon can be used. The medicine helps to correct sleep rhythm and reduce the REM sleep, which results in deep refreshing sleep. Visit your doctor and discuss about these medicines.
For Restless Leg Syndrome (RLS) medicines like Vitamin E supplements can help. Pregabalin or Gabapentin can be utilised for severe RLS symptoms. Try to relax yourself and don't think about not getting good sleep again and you will feel better. Improvement in depressive symptoms and sleep will improve your RLS symptoms.
Thanks, hope this helps you. Please ask again if you have more doubts.
